inter-satellite links

In 2024 the global Optical Inter-Satellite Links (OISL) market was about US$402 million and is projected to reach US$2.0 billion by 2030, a fivefold increase with roughly 30% CAGR. Major LEO mega-constellations such as SpaceX’s Starlink, Amazon’s Project Kuiper, and the planned OneWeb Phase 2 are integrating optical inter-satellite links from the outset to boost capacity and reduce latency. The U.S. Space Development Agency standardizes an optical terminal interface at about 2.5 Gbps and is seeding multiple vendors to build compatible units, jump‑starting a domestic OISL supply chain. China’s Laser Starcom achieved a world-record 400 Gbps laser inter-satellite link test
